The weirdest Christmas traditions

Christmas cards with red colours should be avoided in Japan, however,
as they are associated with death, and red cards are normally sent to the
bereaved.

In Japan, Santa Claus is named "Santa Kurohsu", and is said to have
eyes in the back of his head, to allow him to keep an eye on naughty
children. The Japanese are also fond of Christmas cake, although their
version usually consists of sponge, whipped cream and strawberries.
